FAQ

Frequently Asked Questions
Ground Penetrating Radar (GPR) often referred to as Concrete Scanning or Concrete X-ray, works by sending a pulse of energy into concrete and measuring the strength and time of the returning signal. The equipment will repeat this action multiple times as the unit is maneuvered across a surface and process the returning data points. This processed data will then appear on the operating system's monitor and is interpreted by the GPR Operator.
